Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105084, here are decompositions:
- 13 + 105071 = 105084
- 47 + 105037 = 105084
- 53 + 105031 = 105084
- 61 + 105023 = 105084
- 97 + 104987 = 105084
- 113 + 104971 = 105084
- 131 + 104953 = 105084
- 137 + 104947 = 105084
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 084 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
